how to Select multiple radiobuttons in listview and arranging in arraylist using their positions
Iam having 25 questions with each having 4 options(nothing but 4 radio buttons) selecting on among the four in listview.Iam getting selected position and their radio id accurately but iam unable to keep their position with radio id in arraylist.And one more issue is when listview is scrolled ,the radio buttons checked are misplaced.Please the below and help me.
Thanks in Advance!
Here is my adapter class,please look into it.
public class CustomListAdapter extends BaseAdapter {
private Integer[] listData;
int selectedPosition = -1;
private LayoutInflater mInflater;
public CustomListAdapter(Context context, Integer[] listData) {
super();
this.listData = listData;
mInflater = LayoutInflater.from(context);
validdata = new ArrayList<String>();
int size = values.length;
Log.d("size", "" + size);
for (int i = 0; i < size; i++) {
checked.add(false);
validdata.add("");
checkeddata.add("");
}
}
@Override
public int getCount() {
return listData.length;
}
@Override
public Object getItem(int position) {
return position;
}
@Override
public long getItemId(int position) {
return position;
}
public View getView(final int position, View convertView,
ViewGroup parent) {
final ViewHolder holder;
View view = convertView;
if (view == null) {
view = mInflater.inflate(R.layout.items, null);
holder = new ViewHolder();
holder.headlineView = (TextView) view
.findViewById(R.id.textview1);

ViewHolder mHolder;
// if (convertView == null) {
mHolder = new ViewHolder();
convertView = LayoutInflater.from(mContext).inflate(R.layout.listitems, null);
mHolder.mTextView = (TextView) convertView.findViewById(R.id.textView1);
mHolder.mGroup = (RadioGroup) convertView.findViewById(R.id.radioGroup1);
mHolder.mRedButton1 = (RadioButton) convertView.findViewById(R.id.radio0);
mHolder.mRedButton2 = (RadioButton) convertView.findViewById(R.id.radio1);
mHolder.mRedButton3 = (RadioButton) convertView.findViewById(R.id.radio2);
// convertView.setTag(mHolder);
// }
// else {
// mHolder = (ViewHolder) convertView.getTag();
// }
final MyQuestion mMyQuestion = myQuestions.get(position);
mHolder.mTextView.setText(mMyQuestion.getmQuestion());
int mQuestion_answed = mMyQuestion.getQuestion_answed();
mHolder.mGroup.setOnCheckedChangeListener(null);
if (mQuestion_answed != 0) {
switch (mQuestion_answed) {
case 1:
mHolder.mRedButton1.setChecked(true);
break;
case 2:
mHolder.mRedButton2.setChecked(true);
break;
case 3:
mHolder.mRedButton3.setChecked(true);
break;
default:
break;
}
}
// listener for radioGroup
mHolder.mGroup.setOnCheckedChangeListener(new OnCheckedChangeListener() {
@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
switch (checkedId) {
case R.id.radio0:
mMyQuestion.setQuestion_answed(1);
break;
case R.id.radio1:
mMyQuestion.setQuestion_answed(2);
break;
case R.id.radio2:
mMyQuestion.setQuestion_answed(3);
break;
default:
break;
}
}
});
return convertView;
}
// VIewHolder
private class ViewHolder {
TextView mTextView;
RadioGroup mGroup;
RadioButton mRedButton1, mRedButton2, mRedButton3;
}
// bean class
public class MyQuestion {
private String mQuestion;
private int question_answed;
public MyQuestion() {
super();
}
public String getmQuestion() {
return mQuestion;
}
public void setmQuestion(String mQuestion) {
this.mQuestion = mQuestion;
}
public int getQuestion_answed() {
return question_answed;
}
public void setQuestion_answed(int question_answed) {
this.question_answed = question_answed;
}
}
this is the ArrayList i am using
private ArrayList<MyQuestion> mQuestionsList = new ArrayList<MyQuestion>();
